NEW YORK (CNN) – There is new information about the U.S. planning for possible airstrikes against ISIS in Syria.

From President Obama a threat and a promise, “Justice will be done. We have proved, time and time again, we will do what’s necessary to capture those who harm Americans butt to. We’ll continue to take direct action where needed to protect our people. And to defend our homeland.”

As the U.S. prepares to potential militarily confront ISIS, the pentagon will say little about the reconnaissance flights President Obama authorized over Syria.

“I am not going to talk about intelligence matters.

An administration official tells CNN that drones have flown over Iraq, near the border with Syria, to pick up whatever intelligence they can about ISIS troops, convoys, weapons and training camps just inside Syria,” said Pentagon Press secretary John Kirby.

Anything on targets that could be hit to disrupt their brutal campaign of murder and intimidation.

U.S. satellites have already gathering some information; ISIS communications are also being monitored, but now the U.S. needs to get real time intelligence.

The type of drone being used sources say, a global hawk, it flies at 60,000 feet and is specially equipped to gather targeting information on fixed and mobile targets exactly the type of information on ISIS the U.S. wants.

The U.S. will not acknowledge if drones have penetrated Syrian airspace, a move that would violate Syria’s sovereignty us officials say.

Once the intel is in hand, would U.S. bombers have to cross into Syria to strike? Perhaps. One option: B-1 bombers flying at high altitude, dropping precision bombs, but many say airstrikes alone will not defeat ISIS.

“These isolated military actions can only result in more difficulty. The president needs to put together his national security team with the department of defense and put together a plan,” Secretary Kirby continued.
